This last book from one of Britain's great children's writers (who won the Carnegie Medal in 1958 for Tom's Midnight Garden, and was a commended runner-up four more times) is part detective story and part fairy tale, for readers 7 and up. After Till's dog slips her leash and runs away, he meets Mr. Finder, an odd little man who offers to help him track down the frisky pup. Together they question some likely witnessesóa heron, a mole, a riddling cat, and two sweet old ladiesóbut Finder himself is given to disappearing, and Till wonders if he can be trusted. Philippa Pearce wrote the tale for her grandsons, to be illustrated by their other grandmother, Helen Craig (illustrator of the Angelina Ballerina books).
